Sertraline - Paranoid from dosage change of setraline?

Hey. I take 50mg of trazodone for sleep and was taking 100mg of setraline but got bumped up to 150mg. When I was on 100mg I was lashing out, full on rage mode. Throwing things, screaming at anyone about anything. Now that I got bumped up to 150mg of Setraline I've calmed down some. Here's is where this "thing" started. I've become paranoid. Turning on every light on my way to the bathroom, refusing to go to the kitchen for water at night, feeling like someone's behind me, watching. Always checking my surroundings, and believing people are mad at me for no reason.

I would like to know if this could just be a side effect from the dosage change and if anyone else had this happen to them, if so did it go away? And how long it it take?

I was only diagnosed with depression and social anxiety by my psychologist. And I've never felt paranoid to this level before. And I don't believe it my anxiety, I feels to different.
